Quality Control

Our S-Inosylhomocysteine is produced under stringent quality management systems. Each batch undergoes comprehensive analytical testing including HPLC for purity, spectroscopic identification (NMR, IR), and specific optical rotation verification to ensure identity, potency, and consistency. Certificates of Analysis (COA) detailing all test results are provided with every shipment. We support development and cGMP-grade requirements for advanced research and manufacturing applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive) and light-sensitive; therefore, containers must be kept tightly sealed in a desiccated environment and handled under conditions that minimize exposure to ambient light and humidity to maintain stability and purity.
